Admissible Statement During Concealment
Cynthia Cortez and Charlotte Chung agreed to misrepresent pesticide use on their farms. While disposing of banned barrels, Chung texted a coworker about the plan to avoid detection. The court admitted the text against Cortez because it was made by her coconspirator during and in furtherance of the ongoing concealment.
Recorded Conversations Linking Participants
Cameron Cruz and Cecilia Cabrera discussed falsifying billing records on recorded calls. The prosecution introduced the tapes after showing independent evidence of their agreement. The court treated the statements as admissible against both because each was a coconspirator whose declarations advanced the scheme.

Standing to Challenge Coconspirator Wiretaps

Common questions
Frequently Asked
4
What must the government prove before a coconspirator statement is admitted under Rule 801(d)(2)(E)?+
The court must find by a preponderance of the evidence that a conspiracy existed and that the declarant and the party against whom the statement is offered both participated in it. The coconspirator's own statement may be considered along with other evidence in making that preliminary determination.
Does a coconspirator statement require proof that the declarant is unavailable?+
No. The prosecution need not show that the nontestifying coconspirator is unavailable as a prerequisite to admitting the statement.
When does withdrawal by one coconspirator defeat liability for the conspiracy itself?+
Under traditional common law principles, withdrawal after the agreement and any required overt act does not undo the completed conspiracy offense, although it may limit liability for later substantive crimes committed by others.
Can a person be convicted of conspiracy when the alleged coconspirator only pretended to agree?+
No. Common law conspiracy requires a genuine meeting of the minds in which both participants share the criminal purpose. Feigned agreement by one party defeats the bilateral requirement.
